RAILWAY-CROSSING SIGNAL.

Specification of Letters Patent.

Patented J an. 9, 1912.

Application filed September 21, 1909. Serial No. 518,805.

To all whom it may concern:

Be it known that I, AARON T. CABEEN', a citizen of the United States,residing at Aledo, in the county of Mercer and State of Illinois, haveinvented certain new and useful Improvements in Railway-CrossingSignals, of which the following is a specification.

This invention has relation to certain new and useful improvements inrailway crossing signals.

The object of my invention is to provide an audible alarm for railwaycrossings arranged to be operated by the wheels of the rolling stockpassing over the rails.

Another object is to provide a signal of the class described soconstructed that the same will be silent when actuated by a car wheelapproaching from one direction and be operated when approached from the0pposite direction.

With these and other objects in view, the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described and particularly pointed out in the appended clalms, itbeing understood that changes in the specific structure shown anddescribed may be made within the scope of the claims without departingfrom the spirit of the invention.

In the drawings forming a part of this specification, and in which likenumerals of I reference indicate similar partsin the several views,Figure 1 shows a top view of a railway disclosing the position andlocation of my signal, Fig. 2 is an enlarged sectional detail of thetrip as used in my invention, Fig. 3 is a transverse sectional Viewthrough the mechanism and a rail, Fig. 4 is a perspective view of one ofthe bell clappers, Fig. 5 is an enlarged detached detail of the alarmbell as used in my invention.

My invention comprises an alarm signal arranged to be placed near agrade crossing, bridge or the like to give notice of the approach of anengine or train.

In the accompanying drawings, the numeral 5 designates a stretch oftracks, 6 a grade crossing, 7 the posit-ion of the alarm bell, and 8 and9 the location of the trips.

To a suitable plate 10 arranged to be secured below the base flange ofthe rail 11, I secure the stand 13 as used in my invention provided withthe outwardly extending base 12. This stand has a reduced head 14,carrying a pivot pin 15 and is further provided with the horizontallydisposed slot 16. The base 12 is held in position by means of the bolt17. Pivotally held upon the pin 15, is the trip in the form of a lever.The trip comprises the base 20, the two oppositely positioned sideflanges 21, the obliquely c011- tinued outstanding head 23 which isconnected to the flanges 21 by means of the flanges .24, while theearforming portion 25 is located proximal to the head 23. The earformingportions 25 of the flange are apertured to receive the bolts 15 so thatthis trip may be pivotally held to the stand as disclosed. Passingthrough a suitable opening within the head 23 is one end of theconnecting wire 27, secured by means of the nut 28. Extending upwardfrom the base 12 of the stand, is the staple 30, this staple beingarranged for coactionwith the staple 31 secured to the under surface ofthe trip as clearly disclosed in the drawings. The wire length 27 issecured to a second wire 36, by means of the swivel 35. The staples 30and 31 limit the upward tilt of the trip as shown. To a suitable base 37carrying a bolt 38, is secured the gong 39 as shown in Fig. 4. This basecarries the two supporting pins 40, each pin carrying a similar lever 41each having an aperture at its lower end arranged to receive the end ofthe wire 36 which is secured by means of a nut 42. Each lever 41 whichis in the form of a clapper is provided with the hammer head 43 arrangedto contact with the bell 39, while near the lower end I provide theenlargement or head 44 arranged to receive the supporting pins as shown.Near the upper end each bell lever carries a cup 45, the cups of the twolevers being held in spaced relation and are arranged to receive theexpanding helical spring 46 this spring being arranged to force the belllevers against the rubber buffers 48 held within the cars 49 as shown inFig. 4.

As shown in Fig. 3, the stand and trip are so positioned that the treadof the wheels will contact with the same. The turnbuckle 35 is givensuch adjustment that the trip 20 will be tilted in an upward conditionagainst the tension of the spring 46, which is sufiiciently strong toinsure the two bell levers 41 being held against their elastic buffers48, in such a manner as to insure the levers being held in their extremeupper tilted condition.

The instrumentalities having been properly arranged, should a car wheelapproach and pass over the trip in the direction of the arrow 00, thetrip after being released, would suddenly fly upward causing the tiltingof the bell lever ll against the tension of the spring 46, and in itsreturn movement the hammer 43 would be brought into contact with thegong 39. Every wheel passing over the trip would insure the gong beingstruck once. The buiiers 48 are so positioned that the hammer heads 43do not contact with the bell or gong 39 excepting when tripped. Thiswill insure its revibration of the gong. Should the car wheels approachthe trip from the direction of the arrow y, the trip would be suddenlydepressed, but would be gradually released allowing the bell hammer toslowly approach the buffer 48 so that there would be no ringing of thegong when the trip is tilted from the direction of the arrow 1 From theforegoing it will be seen that the device is arranged to be used inconnection with a single track railroad as well as with a double trackroad. It will be seen that the signal will only be actuated when thetrain is approaching the crossing. The device is simple and inexpensivein construction, and both durable and eflicient in operation. By meansof the turnbuckle 85, the connecting wires or rods can always be held ata proper tension. The wire section 27 is guided within the opening 16,as well as passing through the staple 30.

What is claimed is:

1. In a crossing signal the combination with a stand disposed at asuitable distance from the crossing, of a trip pivotally secured to saidstand having a head, said head being inclined upwardly in the directionof the crossing, means limiting the upward movement of said trip, abase, a gong secured to said base, an elastic stop, a pivotally heldbell lever, a spring to normally force said lever against said stop, andan adjustable connection extending from said trip to said bell lever.

2. In a crossing signal, the combination with a stand having ahorizontal passage, and disposed at a suitable distance from thecrossing, of a trip pivotally secured to said stand having a head, saidhead being inclined upwardly in the direction of the crossing, a stapleextending from said stand, a staple extending from said trip inengagement with said first mentioned staple, a base,

a gong secured to said base, an elastic stop,

a pivotally held bell lever, a spring to normally force said leveragainst said stop and an adjustable connection extending from said tripthrough said horizontal passage and secured to said bell lever.

3. In a crossing signal, the combination with a suitable base, of twopins supported by said base, a bell lever secured to each of said pins,each bell lever having a socket, said sockets being held in spacedrelation, a spring having its ends engaged within said sockets, elasticstops, said spring forcing said levers against said stops, a gong, twooppositely positioned stands, a trip secured to each stand and upwardlyinclining in the direction of said gong and having a down wardlyprojecting end, at its lower extremity, a rod connected to saiddownwardly projecting end of the trip and to one of said levers, a loopon said stand, and a loop on said trip interlinking with said firstnamed loop to limit the upward movement of said tri Th testimon whereofI aflix my signature, in presence 0' two witnesses.
